Curious about this movie.

I remember walking into my mother’s room as a child and seeing her watch something.

I walked in on a scene. And the scene was of a guy in a robe, he had people over like he was having a party. They were cheering and I remember him saying “ok who wants to do the honors.” He had a fountain in front of him, his friend then comes and proceeds to drown him (on purpose)again everyone cheers, for what, I have no clue. Very strange.
